DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, the mixing valve body 9 has a hot water flow passage 10 and a water flow passage 11, and a water flow passage 11 side has a temperature adjusting variable operating force generating means 12 and a temperature adjusting variable operating force generating means 12 is provided. It has an iron core 13 and a coil 14, and the coil 14 is electrically connected to a hot water supply controller 15. It is in contact with the upper end of the valve shaft 16 at the lower end of the iron core 13, and a water valve body 17 and a hot water valve body 18 are fixed to the valve shaft 16 to move integrally with the valve shaft 16 to adjust the flow rates of hot water and water. The hot water and the water are mixed in the mixing unit 19, and the hot water temperature is detected by the temperature detector 20. The signal from the temperature detector 20 is calculated by the hot water supply controller 15, and the hot water supply controller 15 controls the hot water temperature by adjusting the current flowing through the coil 14 so as to reach the set temperature.

The hot water whose temperature has been adjusted as described above flows into the inflow passage 22a of the water amount controller 21 and flows out from the outflow passage 22b. A valve housing 23 is provided with a control valve body 24 for adjusting the flow rate and a valve seat 25 corresponding thereto in the valve housing 23.
In order to balance the primary pressure of the fluid with the control valve body 24, a pressure receiving body 26 is provided so that the effective pressure receiving area becomes equal to the valve seat 25. The back pressure chamber 27 of the pressure receiving body 26 and the secondary side of the control valve body 24 communicate with each other through a communication hole 28, and the control valve body 24 is biased by a spring 30 in a direction of abutting against the valve seat 25. I am energetic. A coil 32 and an iron core 33 are provided as the flow rate adjusting variable operating force generating means 31, and the iron core 33 and the control valve body 24 are connected to each other.

With the above construction, when the coil 32 is not energized, the control valve element 24 abuts on the valve seat 25 by the spring 30, and the fluid does not flow. When the coil 32 is energized, the iron core 33 is attracted, the control valve element 24 is lifted against the biasing force of the spring 30, and the fluid starts to flow. That is, the control valve body 24 is adjusted to an arbitrary lift amount and the flow rate is controlled by changing the amount of electricity supplied to the coil 32. A water quantity setting device 34 is used to manually or automatically set the hot water supply amount, and an electric current is supplied to the coil 32 according to the signal. Reference numeral 35 denotes a signal generator that continuously generates a signal that changes abruptly and that the holding time at the maximum value and the minimum value changes irregularly. The signal generator 35 generates the signal that continuously changes with time. The signal is sent to the hot water supply controller 15 and superimposed on the signal from the water amount setting device 34.

Next, the operation will be described. When current is applied from the hot water supply controller 15 to the coil 32 in accordance with the value of the water amount setting device 34 while the hot water whose temperature is adjusted by the temperature adjusting variable operating force generating means 12 is flowing, the iron core 33 is exposed to the upper part. A directional force is generated to resist the force of the spring 30 and separate the valve body 24 from the valve seat 25 to increase the amount of hot water supplied. The amount of hot water supplied is uniquely determined by the current of the coil 32 and hardly changes even if the primary pressure changes. The signal generator 35 continuously generates a rapidly changing signal, and irregularly changes the holding time at the maximum value and the minimum value thereof. The sum of this signal and the signal from the water quantity setting device 34 becomes the water quantity set value, and the water quantity set value changes with time. The variable operation force generating means 31 for adjusting the flow rate is an electromagnetic type and can adjust the amount of hot water supplied at high speed. As a result, the hot water supply amount changes one after another as shown in FIG.

In FIG. 2, the maximum value and the minimum value of the hot water supply amount are constant, but since the holding time is irregularly changed, various changes can be achieved. Although a rectangular waveform is shown in FIG. 2, even if it takes some time to rise and fall due to operation delay, it does not matter if it is within 1 second. Due to such a sharp change in hot water supply amount and an unpredictable change, a strong stimulus is obtained when the shower is used, which has a massage effect. In this case, since the signal generator 35 only needs to be changed with time, it can be easily configured with a timer or the like.

FIG. 3 shows a second embodiment of the present invention, which is different from the above embodiment only in the signal generator 35, and is otherwise the same in structure and operation as the above embodiment. The signal generator has a constant sharply changing frequency and irregularly changes the levels of its maximum value and minimum value. In this case, it is necessary to control the amount of hot water supplied continuously. Of course, more complicated control can be performed by combining the first embodiment and the second embodiment.

[0014]

As described above, according to the first means of the hot water supply control device of the present invention, the following effects can be obtained. (1) Since the amount of hot water supplied was changed abruptly and the holding time at the maximum and minimum values was changed irregularly, a strong stimulus was obtained due to the abrupt change, and the massage effect was great if used in the shower, And since it has irregularities rather than simple repetitions, unpredictable fresh stimuli are continuously obtained without habituation. Moreover, complicated changes can be easily made only by changing the holding time.

According to the second means of the hot water supply control device of the present invention, the following effects can be obtained. (1) Since the amount of hot water supply is changed abruptly and the levels of the maximum value and the minimum value thereof are changed irregularly, a change due to the abrupt change is obtained, and a simple rhythm is not maintained while maintaining a constant rhythm. So I don't get used to it.
